Advanced Nanotechnology Approaches in Water Purification: Photocatalytic Degradation of Coralene Blue BGFS Dye Using Magnesium Zinc Aluminate Nanoparticles

Textile effluents contain major content of dye molecules as well as toxic chemicals and contribute to water pollution. The dyeing and finishing processes in industries consume large quantities of water, and the dyes commonly used are toxic and resistant to biodegradation. Coralene Blue BGFS are widely used in biological staining, printing and dyeing, leather, ink, lithography, etc. A comprehensive study was conducted on the photocatalytic degradation of Coralene Blue BGFS dye solutions. MgZnAl2O5 nanoparticles were synthesized using urea (NH2CONH2) through the solution combustion method. These nanoparticles were characterized using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and UV absorbance spectroscopy. The average size of the nanoparticles was determined to be 23 nm, with a band gap of 3.0 eV. The photocatalytic degradation efficiency of the nanoparticles was evaluated by varying parameters such as catalyst concentration, pH, dye concentration, and UV light exposure at 254 nm. The experimental results demonstrated that the maximum photodegradation of Coralene Blue BGFS reached 98.12% at pH 10 under UV light exposure. The method of photocatalytic degradation of Coralene Blue BGFS is more helpful in treating Coralene Blue BGFS dye-containing textile effluents. The method is environmentally friendly, easily adaptable to dye degradation techniques under UV light, and suitable for large-scale applications.
